Wetlands. WETLAND HYDROLOGY. Wetland hydrology is the second wetland parameter. The term wetland hydrology encompasses, all hydrological characteristics of areas that are periodically inundated or have soils saturated to the surface at some time during the growing season.reas with evident characteristics of wetland hydrology are those where the presence of water has an overriding influence on characteristics of vegetation and soils due to anaerobic and reducing conditions respectively, (U.S. Army Corps of Engineers 1987).

Hydrology. Hydrology = study of patterns of water movement. -extremely important for the maintenance of a wetland's structure and function. Hydrologic conditions affect many abiotic factors such as soil aeration, nutrient availability, and salinity.which then affect flora and fauna which then alter hydrology.Hydrology is probably the most important determinant of the establishment and maintenance of specific types of wetlands and wetland processes*. Remember that wetlands represent the aquatic edge of terrestrial (emergent) plants and the terrestrial edge of aquatic (submersed) plants and animals.

-Mitsch and Gosselink (1993). Wetland hydrology is perhaps the most key element in all wetland restoration project. Many wetland scientists have referred to wetland hydrology as the most important component of wetland ecosystems (Mitsch and Gosselink, 1993; Erwin, 1990 in Kusler and Kentula, 1990).o see a case study of wetland hydrology manipulation, click here. Small changes is wetland hydrology can significantly affect the chemical and physical properties of a wetland such as nutrient availability, degree of substrate anoxia, soil salinity, sediment properties, and pH (Mitsch and Gosselink, 1993).

1 In addition, because each wetland is uniquely situated within the landscape, wetland hydrology will be somewhat unique to all wetland types. 2  The hydrological regime of each wetland differs in frequency and magnitude of high water, duration, timing, and temporal sequences of high and low water (Zedler, 2000).o see a case study of wetland hydrology manipulation, click here. Small changes is wetland hydrology can significantly affect the chemical and physical properties of a wetland such as nutrient availability, degree of substrate anoxia, soil salinity, sediment properties, and pH (Mitsch and Gosselink, 1993).

Areas with evident characteristics of wetland hydrology are those where the presence of water has an overriding influence on characteristics of vegetation and soils due to anaerobic and reducing conditions respectively, (U.S. Army Corps of Engineers 1987).Hydrology is usually the least exact of the three parameters.reas with evident characteristics of wetland hydrology are those where the presence of water has an overriding influence on characteristics of vegetation and soils due to anaerobic and reducing conditions respectively, (U.S. Army Corps of Engineers 1987).

Wetland Hydrology Today. Humans have altered wetland hydrology through a variety of activities: drainage, filling, damn construction, water diversions, groundwater pumping, and dredging (Zedler, 2000). All of these activities alter the timing, amplitude, frequency, and duration of high water (Zedler, 2000).o see a case study of wetland hydrology manipulation, click here. Small changes is wetland hydrology can significantly affect the chemical and physical properties of a wetland such as nutrient availability, degree of substrate anoxia, soil salinity, sediment properties, and pH (Mitsch and Gosselink, 1993).

The formation, persistence, size, and function of wetlands are controlled by hydrologic processes. Distribution and differences in wetland type, vegetative composition, and soil type are caused primarily by geology, topography, and climate.Differences also are the product of the movement of water through or within the wetland, water quality, and the degree of natural or human-induced disturbance.round-water recharge and discharge are hydrologic processes that occur throughout the landscape and are not unique functions of wetlands. Recharge and discharge in wetlands are strongly influenced by local hydrogeology, topographic position, ET, wetland soils, season, and climate.

Wetlands are complex ecosystems in which ground water and surface water interact, but because ground water cannot be directly observed, its role in the hydrology of wetlands is sometimes more difficult to understand than that of surface water.round-water recharge and discharge are hydrologic processes that occur throughout the landscape and are not unique functions of wetlands. Recharge and discharge in wetlands are strongly influenced by local hydrogeology, topographic position, ET, wetland soils, season, and climate.

Hydrologic processes occurring in wetlands are the same processes that occur outside of wetlands and collectively are referred to as the hydrologic cycle. Major components of the hydrologic cycle are precipitation, surface-water flow, ground-water flow, and evapotranspiration (ET).round-water recharge and discharge are hydrologic processes that occur throughout the landscape and are not unique functions of wetlands. Recharge and discharge in wetlands are strongly influenced by local hydrogeology, topographic position, ET, wetland soils, season, and climate.

The hydroperiod or hydrologic signature of a wetland is the balance between inflows and outflows of water (the water budget), the soil contours, and the subsurface conditions.Hydrology is probably the most important determinant of the establishment and maintenance of specific types of wetlands and wetland processes*. Remember that wetlands represent the aquatic edge of terrestrial (emergent) plants and the terrestrial edge of aquatic (submersed) plants and animals.

the importance of hydrology at a wetland
The importance of hydrology at a wetland is that all hydrological characteristics of areas that are periodically inundated or have soils saturated to the surface at some time during the growing season.
