“…However, prediction of water quality dynamics accounting for physical-chemical-biological interactions is limited. The present study found only three studies based on hydrodynamic-ecosystem assessments of lakes (Talib et al 2012;Hasan et al 2013;Sharip et al 2016). One study on phosphorus loading estimation was identified, which used a Vollenweider model to predict the capacity of lakes to assimilate pollutants, particularly nutrients (Shamsudin et al 2008).…”

The deterioration of water quality in lakes resulting from unsustainable catchment practices requires concerted efforts to address them, in the form of cooperation among government agencies and institutions, private bodies and the community‐at‐large. Research that provides an understanding of a lake's ecosystem is an important aspect of making informed decisions for sustainable management and governance of lakes. The present study describes the findings of literature reviews on Malaysian lakes, and the national efforts made to establish an agenda for lake research and development in Malaysia directed towards integrated lake basin management (ILBM). The main findings and outcomes of the National Lake Research Blueprint workshop in April 2014 on the issues facing lakes and reservoirs are highlighted. Seven research themes were identified, namely (i) ecosystem services and socio‐economic development, (ii) governance, (iii) water quality and pollution, (iv) eco‐hydrology and basin management, (v) biodiversity and natural products, (vi) physical limnology and hydrodynamics and (vii) technology. The goal is to enhance research and development on sustainable lake basin management directed to conservation and development targets. The findings of this study provide an integrated research framework that can support ILBM governance elements (pillars) elsewhere, and to call for researchers to participate in much‐needed research areas.

Hydrodynamic simulations using three-dimensional numerical model were carried out in three different shallow tropical lakes to understand the characteristics of water movement in the respective water bodies. The models were based on meteorological data from the nearest stations and calibrated with current measurement, temperature, or water-level data. The results show good agreement between measured and simulated velocities and/ or temperature at certain depth. This study found that the major driving forces of the hydrodynamic pattern were different in the three lakes. Hydrodynamic simulations showed that Bukit Merah and Durian Tunggal reservoirs were more sensitive to winddriven motion. Floodplain lakes, such as Bera Lake, are more sensitive to flood inflow by the main river during the monsoon season. Convective motion driven by water temperature gradient was important for Bukit Merah and Bera Lake.

“…Similarly, a few studies on model development in relation to lakes have only focused on nutrient response models for shallow tropical lake (Sharip, Schooler, Hipsey, & Hobbs, ), eutrophication (Ishak, ) and water quality assessment of urban recreational lakes, which omit the watershed and surrounding land‐use influences (Oyekanmi, Nik Daud, Ahsan, & Pradhan, ). Recent studies (Ali et al., ; Sharip, Yanagawa, & Terasawa, ; Sharip, Saman, et al., ) focused only on water demand issues, assessment of spatial water quality dynamics and lake ecosystem dynamics in response to nutrient fluxes, respectively, using the application of commercial software.…”

Development of spatial similarity‐based modelling to improve integrated lake water quality management in Malaysia

et al. 2018

This study describes similarity‐based modelling techniques used to develop a spatially based water quality prediction model to facilitate sustainable lake water quality management. The lentic nature of lakes allows them to slowly absorb pollutants over a long period of time with readily noticeable signs, causing symptoms to appear only when the water quality has significantly degraded, meaning the risk of improper water quality management can be very high. Thus, failure to establish sustainable planning at the watershed scale was found to be a major threat of water quality degradation, from extemporary approaches often practised in lake management. Accordingly, the developed model is tailored for lakes facing moderate to serious water quality data limitation. The geodatabase integrates the identified driving factors of physical, social and water quality with significant influences on the status of lake water quality. A 1 km buffer radius with percentages of built‐up area, population, lake surface area and rainfall is measured. Calculation of a water quality index was then quantified on the basis of a similarity‐modelling technique. Lake Putrajaya was chosen as a control point for developing the indicator index. A total of 93 recreational lakes within Selangor and Kuala Lumpur were selected as modelling points. The results of this study indicated the similarity technique of spatial modelling is sufficiently reliable to be applied as an early assessment indicator. From the 93 lakes in this study, none feel in the category of either “bad” or “excellent,” with the majority being in class 3 (medium water quality status) and only four considered as having a good water quality condition. The balance of 35 lakes was considered to exhibit poor water quality. The model output is an indicator index, providing classification guidelines for the water quality status of the assessed lake as an early assessment tools.
