Classification of Soil Water
Published in A. Zaman, Md. Hedayetullah, Sustainable Water Resource Development and Management, 2022
Lakes are connected with rivers through the hydrological cycle. Lakes have many origins; major lakes are usually formed by glacial erosion or through tectonic activity. Lakes are versatile and it has many use and lakes tend to be deep. Shallow lake with high levels of biodiversity during the middle of the 20th century that time dam building R accelerated to the point where over 65% of the world’s rivers are now regulated. The impacts of this regulation are widespread and include detrimental hydrological, ecological, geomorphological, and socioeconomic effects. Year after year it develops a reverence for rivers and lakes, and recognize the interdependence of all biodiversity.
Simulation and application of eutrophication in Hongze Lake

Eutrophication is the most common and serious water environment problem in today's lakes and reservoirs. China has now become one of the countries with the most serious lake and reservoir pollution and algal blooms in the world (Farnaz et al. 2019; Ma et al. 2020; Yahyaee et al. 2021; Wang et al. 2019). At present, most lakes are already eutrophic and mesotrophic lakes. The existence of eutrophication in lakes has seriously hindered the utilization of these water bodies as resources, resulting in heavy environmental and economic losses. Hongze Lake is the first lake for regulation and storage in the east route of the South-to-North Water Diversion Project. However, Hongze Lake is affected by the water transfer from the Yangtze River and the incoming water from the Huai River. The water quality of Hongze Lake is poor, and the eutrophication problem is more serious. Nitrogen and phosphorus have become the main pollutants of Hongze Lake (Yao et al. 2022). This paper takes the EFDC model as an example to simulate the eutrophication of Hongze Lake.

In addition to these religious beliefs, lakes also provide a space for recreational activities for both traditional village communities as well as other urban residents living around them. Walking, jogging and angling are common recreational activities to be seen around lakes. Villagers also gather around community spaces built around lakes to interact with each other over the day.
Effect of alternative regional urban growth scenarios on a major urban lake

Lakes are a multifunctional component of the urban space and an important source of ecosystem services, such as recreation, fishing, drinking water, and wildlife habitat (Schallenberg et al. 2013, Grizzetti et al. 2016). Environmental changes driven by urban development put pressure on aquatic ecosystems, which can lead to degradation of ecosystem services (Keeler et al. 2012, Carstens and Amer 2019). Rapid urbanization increases the demand for ecosystem services that urban lakes provide and exacerbates the vulnerability of these ecosystems to anthropogenic degradation. Maintaining ecosystem services to sustain growing urban needs is one of the greatest challenges to the sustainable development of cities (Grunewald and Bastian 2017). The failure to forecast the impact of future urbanization on ecosystem services lakes provide could result in the progressive loss of benefits.
Paleolimnological assessment of six lakes on the Kissimmee Chain, with implications for restoration of the Kissimmee–Okeechobee–Everglades system, Florida, USA

Current management approaches often emphasize in-lake nutrient concentrations and mitigation without adequately considering other significant changes in ecology or ecosystem function, but restoration cannot be effective when it regards system changes as univariate (Davidson et al. 2018). Contemporary challenges for management of these lakes include satisfying stakeholder needs related to the sport-fishing economy, recreational uses, water supply, and flood prevention. The lakes, however, are distinctly out of balance with respect to nutrient content and recycling, standing crops of native and invasive plants, and the accumulation of nutrient-rich organic sediments. Considerable energy and costs are required for periodic drawdowns, scraping of sediments, and management of aquatic plants. The sustained connection of the lakes, which originated as a 19th-century paradigm, also facilitates transport of nutrients through the Kissimmee–Okeechobee–Everglades system, and it contributes to downstream restoration challenges.
Segmentation of Mississippi’s natural and artificial lakes

Commonly, lake segmentations are developed intuitively based on lake origin and size. A typical origin dichotomy is the natural vs. artificial split. This split has been applied by various authors to study lake characteristics (e.g., Canfield and Bachman 1981, Jones et al. 2008) and by the U.S. Environmental Protection Agency to target sample lakes in their recurrent National Lake Assessment (Peck et al. 2013). Natural lakes originate from various sources including glaciation, tectonics, earthquakes, wind, dissolution of limestone, and meandering rivers. Artificial lakes are reservoirs constructed for hydropower, flood control, navigation, and water supply, most commonly achieved by building a dam across a river. A second gradient is size (Downing et al. 2006, McDonald et al. 2012). Both natural and artificial lakes range widely in surface area, and often exhibit right-skewed distributions with few large lakes and many small ones (Lehner and Döll 2004).
