Abstract:

Torrent control works have always been a fundamental tool for preventing torrential hazard in mountain catchments, where the sediment transport phenomena as debris flows are one of the most dangerous geomorphic processes affecting small steep basins. The linkages between sediment source areas on the hillslopes and channel network, along with the temporal and spatial distributions of channel storage, are key controls of debris-flow occurrence and magnitude. Consequently, the prevention of natural hazards related to debris-flows requires a better understanding of sediment dynamic. Among the hydr

Abstract:

Watershed restoration comes in a variety of forms depending on which set of problems are sought to be remedied. Severe soil erosion, in the form of gullying and/or headcutting, can be mitigated through constructing check dams in well-selected locations. This practice has been used throughout the upland subwatersheds within the Upper Laja River watershed in Guanajuato, México. The present study employed Wolman pebble counts to systematically assess the effectiveness of 21 check dams located near the city of San Miguel de Allende.

During the last few decades, many sedimentological distributed models were developed and applied for a wide range of climates a

碩士<br>逢甲大學<br>土木及水利工程所<br>91<br>This experimental study is on the effects of energy dissipation induced by a grid attached to the overflow edge of a check dam upon the scour hole. The variables involved in the hydraulic experiments are length of the grid beam, width of slot between the grid beams, type of the grid beam, roughness of the beam surface and flow rate. Based on the experimental results, it is found that the addition of the grid to the traditional check dam crest can really lessen the scour hole. Among the types of the grid beam used in the experiments, the one with a triangular

Nevertheless, environment conditions of Taiwan’s river are high in bed load and suspension load both, hence close check dam which trap all kind of sand or slit is usually full and losing its ability of trapping after few storms. Slit check dam is permeable dam, so it can prevent from depositing all of sand or slit coming from upstream river in non-flood period. However, in recent years, Japan’s research showed that slit check dam of mode of deposit causing

碩士<br>逢甲大學<br>水利工程與資源保育研究所<br>99<br>The installation of the check dam has a significant impact on habitat variation. Therefore, this research selected a fully-deposited check dam as an object for study. The FLOW-3D model was used to simulate the flow fields around the check dam before and after the check dam improvement. The variations of the channel bed longitudinal and transverse stabilities under six different patterns of check dam removals were used as indications. The check dam removal patterns considered including un-removal, horizontal removal (d/4, d/2), vertical removal (b/4, b/2), an

The model separately estimated the flow rates at the trapezoidal spillway and the rectangular opening below the spillway. A linear combination of both flow rates was used to estimate the total flow rate of the dam. Considering the flow conditions varied with the ration of the water depth and the length of dam. the flow conditions of the check dam were grouped into the broad-crested weir condition and the sharp-crested weir condition based on the aforemention

Its main functions include storing debris, adjusting sediment transport, preventing erosion, controlling stream flow and inhibiting debris. The number of check dam in Taiwan exceeds one thousand, but its lifetime is usually very short. Both safety and practicality were over emphasized on the construction of check dams in the past, and filled the original natural environment was destroyed.

Its main functions are to intercept the coarse sediments, regulate sediment transportation, prevent erosions and restrain the debris flow. However, it also causes a great influence to the river ecosystem. In recent years, check dam improvement becomes a very important issue due to the flood prevention and river ecological restoration considerations. There are many successful experiences of dam removal for ecological restoration in the foreign countries. However, it is still an eme

This new design combines Counterfort Retaining Wall and reinforced concrete for their benefits of low cost and high tension-resistance. Four sections were included in the research: designs of dam configuration, analysis of stability, flume experiment, and cost analysis. In the flume experiment of "Gravity Check Dam of Rei
