River regulation

May-June runoff peaks, 2 to 2.5 times the aimual average nmoff in the 1915-1924 period prior to dam construction, were barely 1.5 times the average flow between 1985 and 1994. Meanwhile, autumn low flows during the 1985-1994 period are close to the mean annual flow, compared to low flows at about half the mean prior to river regulation.

Water temperature modification is an important consequence of river regulation. We can consider that there are two types of impacts on the thermal regime direct and indirect alterations. The direct alterations are those in which there is a direct modification of the temperature of water, mainly through the release of water at a temperature different from the expectable in natural conditions. The indirect...

Among various applications of explosives to engineering work such as tunnel and road building, water front, harbour and river regulation etc., explosive working of metals was recently added to the list of peaceful uses of explosives [97]. 

In the solid runoff of other rivers, regulated owing to the construction of reservoirs, biogenic supply has a greater significance. While in the near-shore zone at low depths the proportion of the biogenic matter ranges from 30 to 50% of the total sediment, the proportion of coquina and detritus in the sediments of the central zone of the northwestern part of the sea reaches 80% and more.

Some coastal environments may be regarded as rather stable (rock and reef coasts) while others are more vulnerable (sand and mud coasts, soft cliffs). In this last case, coastal users and managers aU over the world are frequently faced with serious erosion of their sandy coasts. Possible causes of erosion include natural processes (i.e., action of waves, tides, currents, sea level rise, etc.) and sediment deficit due to human impact (i.e., river regulations, sand mining, and coastal engineering works). Countermeasmes for beach erosion control function depend on local conditions of shore and beach, coastal chmate, and sediment transport. Continuous maintenance and improvement of the coasthnes, together with monitoring and studies of coastal processes have yielded considerable experience on various coastal protection measures all over the world.
