text: Water quality and hypoxia in lakes and reservoirs are strongly associated
with water renewal. Yet vertical water exchange is still not fully understood
and challenging to evaluate in highly dynamic systems. Here, we applied a scaling
approach using the vertical timescale, vertical water age (VWA), defined as time
since a water parcel last touched the water surface. We established a 3D hydrodynamic-based
age model to quantify the vertical water renewal in Xiangxi Bay, a tributary bay
of the Three Gorges Dam. The integrated effects of hydrodynamic processes like
stratification, intruding density currents from the mainstream, and upstream inflow
on the vertical renewal were accounted for. Results indicated that the spatial–temporal
distribution of VWA in Xiangxi Bay depended on stratification and forms of intruding
density currents. Age was large in spring and summer, and small in autumn and
winter, reaching a maximum of 25 days in April. The vertical water renewal was
faster during bottom intrusions from the mainstream than during middle and surface
intrusions. At times, the epilimnion contained old water due to circulations,
and the hypolimnion contained young water due to upstream flushing. In contrast
to natural lakes, the bottom water was often younger than overlying intermediate
waters. This demonstrated that mixed layer depth was insufficient to fully capture
the vertical exchange in riverine systems with significant surface/bottom intrusion.
The findings suggested VWA as a quantitative measure of vertical water transport
in highly dynamic systems and its usability for environmental water management.

text: Water-level reduction frequently occurs in deep reservoirs, but its effect
on dissolved oxygen concentration is not well understood. In this study we used
a well-established water quality model to illustrate effects of water level dynamics
on oxygen concentration in Rappbode Reservoir, Germany. We then systematically
elucidated the potential of selective withdrawal to control hypoxia under changing
water levels. Our results documented a gradual decrease of hypolimnetic oxygen
concentration under decreasing water level, and hypoxia occurred when the initial
level was lower than 410 m a.s.l (71 m relative to the reservoir bottom). We also
suggested that changes of hypoxic region, under increasing hypolimnetic withdrawal
discharge, followed a unimodal trajectory with the maximum hypoxic area projected
under the discharge between 3 m3/sec and 4 m3/sec. Besides, our results illustrated
the extent of hypoxia was most effectively inhibited if the withdrawal strategy
was applied at the end of stratification with the outlet elevation at the deepest
part of the reservoir. Moreover, hypoxia can be totally avoided under a hybrid
elevation withdrawal strategy using surface withdrawal during early and mid stratification,
and deep withdrawal at the end of stratification. We further confirmed the decisive
role of thermal structure in the formation of hypoxia under water-level reduction
and withdrawal strategies. We believe the conclusions from this study can be applied
to many deep waters in the temperate zone, and the results should guide stakeholders
to mitigate negative impacts of hypoxia on aquatic ecosystems.

text: 'Lake Sevan is the largest freshwater body in the Caucasus region, situated
at an altitude of 1,900 m asl. While it is a major water resource in the whole
region, Lake Sevan has received little attention in international limnological
literature. Although recent studies pointed to algal blooms and negative impacts
of climate change and eutrophication, the physical controls on thermal dynamics
have not been characterized and model-based assessments of climate change impacts
are lacking. We compiled a decade of historical data for meteorological conditions
and temperature dynamics in Lake Sevan and used a one-dimensional hydrodynamic
model (GLM 3.1) in order to study thermal structure, the stratification phenology
and their meteorological drivers in this large mountain lake. We then evaluated
the representativeness of meteorological data products covering almost 4 decades
(EWEMBI-dataset: 1979-2016) for driving the model and found that these data are
well suited to restore long term thermal dynamics in Lake Sevan. This established
model setting allowed us to identify major changes in Lake Sevan’s stratification
in response to changing meteorological conditions as expected from ongoing climate
change. Our results point to a changing mixing type from dimictic to monomictic
as Lake Sevan will experience prolonged summer stratification periods and more
stable stratification. These projected changes in stratification must be included
in long-term management perspectives as they will intensify water quality deteriorations
like surface algal blooms or deep water anoxia.'

text: The modelling community has identified challenges for the integration and
assessment of lake models due to the diversity of modelling approaches and lakes.
In this study, we develop and assess a one-dimensional lake model and apply it
to 32 lakes from a global observatory network. The data set included lakes over
broad ranges in latitude, climatic zones, size, residence time, mixing regime
and trophic level. Model performance was evaluated using several error assessment
metrics, and a sensitivity analysis was conducted for nine parameters that governed
the surface heat exchange and mixing efficiency. There was low correlation between
input data uncertainty and model performance and predictions of temperature were
less sensitive to model parameters than prediction of thermocline depth and Schmidt
stability. The study provides guidance to where the general model approach and
associated assumptions work, and cases where adjustments to model parameterisations
and/or structure are required.

text: 'Hutchinson and Löffler''s (1956) classification of lakes based on the seasonal
thermal mixing regime has become a cornerstone of any analysis of lakes as elements
of the earth surface. Until now however the lake classification has lacked a physically
sound quantitative criterion distinguishing between two fundamental lake types:
thermally stratified during a large portion of the year (mono- and dimictic) and
predominantly mixed to the bottom (polymictic). Using the mechanistic balance
between potential and kinetic energy we review the different formulations of the
Richardson number to derive a generalized scaling for seasonal stratification
in a closed lake basin. The scaling parameter is the critical mean basin depth,
Hcrit, that delineates lakes that mix regularly from those that stratify seasonally
based on lake water transparency, lake length, and an annual mean estimate for
the Monin-Obukhov length. We validate the scaling on available data of lakes worldwide
using logistic regression. The scaling criterion consistently described the mixing
regime significantly better than either the conventional unbounded basin scaling
or a simple depth threshold. Thus, the generalized scaling is universal for freshwater
lakes and allows the seasonal mixing regime to be estimated without numerically
solving the heat transport equations.'

text: We investigated the combined effects of thermal pollution from a nuclear power
plant (NPP) and regional climate warming on the thermal regime of a lake. For
this purpose, we used the lake model FLake and analyzed 50 years of temperature
data from Lake Stechlin, Germany, which served as the cooling water reservoir
for the Rheinsberg NPP from 1966 until 1990. Both modeling and statistical data
analysis revealed a strong influence of the NPP cooling water discharge on the
lake water temperatures and the vertical stability of the water column. A remarkable
effect of thermal pollution consisted of strong vertical mixing in winter produced
by the discharge of warm water into the lake when ambient water temperatures were
below 4 °C. This effect caused a significant increase in the deep hypolimnion
temperatures and a corresponding decrease of the vertical stability in the summer.
In turn, climate warming had the opposite effect on the summer stability by increasing
lake surface temperatures. Both the thermal pollution and climate change increased
the duration of the summer stratification period. Our results suggest that industrial
thermal pollution in temperate lakes during winter is stored in the deep water
column until the next winter, whereas heat added in the summer dissipates relatively
rapidly into the atmosphere. Accordingly, the winter thermal pollution could have
a long-lasting effect on the lake ecology by affecting benthic biogeochemical
processes.
