The hydrological controls on vegetation dynamics and wildlife in the mayas wetlands of the Dinder National Park
Published in Khalid Elnour Ali Hassaballah, Land Degradation in the Dinder and Rahad Basins, 2021
As a summary from many papers in the field of ecohydrology, Zalewski et al. (2016) concluded that ecohydrology becomes an important bridge between ecology and environmental management at the catchment scale. As part of a basin-wide management, wetland ecosystem management is important to sustain the ecosystem integrity by protecting indigenous biodiversity and the ecological evolutionary processes that create and maintain that diversity. Challenged with the complexity inherent in natural ecosystems, achieving that goal will require that decision makers clearly describe anticipated ecosystem structure, role, and variability; illustrate differences between present and wanted conditions; define ecologically relevant and measurable indicators that can observe development toward ecosystem restoration, conservation and management goals (Noss, 1990; Cairns et al., 1993; Keddy et al., 1993; Dale and Beyeler, 2001; Carignan and Villard, 2002); and include adaptive strategies into resource management plans (Holling, 1978). If a wetland has continued filling and draining, its integrity is not necessarily preserved, nor is safe from future degradation. Wetlands degradation could be caused by hydrological alterations, sedimentation, salinization, eutrophication and exotic species invasions (Zedler and Kercher, 2005).
Ecohydrology of urban aquatic ecosystems for healthy cities
Published in Iwona Wagner, Jiri Marsalek, Pascal Breil, Aquatic Habitats in Sustainable Urban Water Management, 2014
Ecohydrology is a scientific concept that quantifies and explains relationships between hydrological processes and biotic dynamics at a catchment scale and is applied to solving environmental problems (Zalewski, 2006). It has been defined as a subdiscipline of hydrology focused on ecological aspects of the water cycle. This concept is based on the assumption that the sustainable development of water resources is dependent on the ability to restore and maintain the evolutionarily established processes of water and nutrient circulation and energy flows at the catchment scale.

Ecohydrology is a trans-disciplinary approach, using the understanding of relationships between hydrological and biological processes at the catchment level to improve water quality, biodiversity and sustainable development (Zalewski, 2006; Wagner et al., 2007). The implementation of this approach is based on the restoration and maintenance of water circulation patterns, nutrient cycles and energy flows at a catchment scale towards optimization of the ecosystem services for society (Zalewski and Wagner, 2008). The main areas for ecohydrology applications include the following: 1) Increasing the water catchment, retention and flow duration through the maintenance of existing forest cover, reforestation, and wetland protection; 2) decreasing the loading of non-point pollution by soil conservation and maintaining riparian vegetation along stream courses; 3) maintaining in-stream habitat by the maintenance/restoration of natural river channels and floodplains, ensuring a natural seasonal flow regime; 4) employing biogeochemical processes in natural and constructed wetlands to treat organic matter and nutrient-laden sewage (Saha and Setegn, 2015). A watershed planning and management strategy within a hydrologically defined area provides a coordinated framework for water supply protection, pollution prevention, and ecosystem preservation. Although watershed strategies vary, they should be based on an integrated study of ecosystems and hydrological characteristics, processes and their combined potential to influence water dynamics and quality. Ecohydrology requires an understanding of temporal and spatial patterns of catchment-scale water dynamics, which are determined by four fundamental components: climate, geomorphology, plant cover/biota dynamics, and anthropogenic modifications (UNEP, 2003).

The definitions and scope of use of ecohydrology and hydroecology were already proposed by Wood et al. (2008b). Various definitions of ecohydrology have been provided since the early 2000, when discussion on this concept started (Nuttle 2002). From “the study of the functional inter-relationships between hydrology and biota at the catchment scale as a new approach to achieving sustainable management of water” (Zalewski 2000b) to “the science of integrating hydrological and biological processes over varied spatial and temporal scales” (Bonacci et al. 2009), ecohydrology has been defined as a new paradigm providing a holistic approach to water resources management.

At the end of the twentieth century, wetland models (WM) focused on the dynamics of hydrological variables such as precipitation, infiltration, evapotranspiration that determine the precipitation process, runoff and the volume of water stored on a daily or annual scale (Hammer and Kadlec 1986). For the comprehension of the hydrological aspects within the ecology, ecohydrology is an application-driven interdiscipline and aims to better understand the hydrological factors that determine the natural development of wet ecosystems, concerning their functional value for protection, and restoration of nature (Wassen and Grootjans 1996).

In addition, the hydrological connectivity of a river basin plays an important role in the impact that these stressors have on the freshwater and riparian ecosystems throughout the basin (Leroy Poff & Zimmermann, 2010; Nadeau & Cable Rains, 2007; Pringle, 2003). The interaction between hydrology and ecology, also referred to as ecohydrology, is an important carrier for realizing healthy freshwater ecosystems (Allan, 2012).
