“…It may be most useful to frame these impacts through a comparison of our results described above to the hydrologic effects of larger projects. Magilligan and Nislow (2005) reported the greatest changes to the natural regime among 21 river systems with large-scale dams as reduced high-flow magnitudes, a point that was reiterated consistently in case studies (Ligon et al, 1995;Richter et al, 1996;Batalla et al, 2004;Grams and Schmidt, 2002;Marston et al, 2005;Page et al, 2005). In addition, large water projects commonly alter the rate of change of peak flows.…”

Though many river studies have documented the impacts of large water projects on stream hydrology, few have described the effects of dispersed, small-scale water projects on streamflow or aquatic ecosystems. We used streamflow and air temperature data collected in the northern California wine country to characterize the influence of small instream diversions on streamflow. On cold spring mornings when air temperatures approached 08C, flow in streams draining catchments with upstream vineyards receded abruptly, by as much as 95% over hours, corresponding to times when water is used to protect grape buds from freezing; flow rose to near previous levels following periods of water need. Streams with no upstream vineyards showed no such changes in flow. Flow was also depressed in reaches below vineyards on hot summer days, when grape growers commonly use water for heat protection. Our results demonstrate that the changes in flow caused by dispersed small instream diversions may be brief in duration, requiring continuous short-interval monitoring to adequately describe how such diversions affect the flow regime. Depending on the timing and abundance of such diversions in a drainage network, the changes in streamflow they cause may be an important limiting factor to valued biotic resources throughout the region.

“…Natural and artificial dams upset stream flow regime by trapping sediment and impeding the flow of water. According to the extensive literature on the geomorphic effects of reservoirs, following adjustments can be expected following river impoundment: decreases in peak flows, bed load discharge, width and bank full crosssectional area, floodplain zone; increases or decreases in depth, gradient and sinuosity [23]. According to the fact that dam affects flood zone map, effect of storage reservoir on the river discharge during flood event and flood zone map has been regarded in this research.…”

High flood occurrences with large environmental damages have a growing trend in Iran. Dynamic movements of water during a flood cause different environmental damages in geographical areas with different characteristics such as topographic conditions. In general, environmental effects and damages caused by a flood in an area can be investigated from different points of view. The current essay is aiming at detecting environmental effects of flood occurrences in Halilrood catchment area of Kerman province in Iran using flood zone mapping techniques. The intended flood zone map was introduced in four steps. Steps 1 to 3 pave the way to calculate and estimate flood zone map in the understudy area while step 4 determines the estimation of environmental effects of flood occurrence. Based on our studies, wide range of accuracy for estimating the environmental effects of flood occurrence was introduced by using of flood zone mapping techniques. Moreover, it was identified that the existence of Jiroft dam in the study area can decrease flood zone from 260 hectares to 225 hectares and also it can decrease 20% of flood peak intensity. As a result, 14% of flood zone in the study area can be saved environmentally.

“…The changes in flow regime and reduction of peak discharges caused by regulation have resulted in changes in channel and bottomland dynamics and alteration of riparian-zone vegetation (Stanford et al, 1996;Stanford and Ward, 2001;Hauer and Lorand, 2004). Detailed analyses of vegetation changes that have occurred as functions of time and distance downstream from a dam have been reported, among others, by Johnson (1994) for the Platte River in central Nebraska, by Richter et al (1996) for the lower Roanoke River in North Carolina, by Scott et al (1997) for the Missouri River in Montana, by Marston et al (2005) for the Snake River in Grand Teton National Park, and regionally for the Great Plains by Friedman et al (1998). The complexity of riparian-forest response to river regulation was demonstrated regionally for the Great Plains by Friedman et al (1998), who related stream regulation and consequent channel narrowing along braided streams to increased rates of pioneer-tree establishment along formerly meandering channels in the southern Great Plains.…”
