Abstract:
Recently, many mountain disasters caused by natural phenomena, such as typhoons and heavy rains, have struck Japan, where check dams are used as important disaster prevention structures. Meanwhile, increased timber use in Japan is expected to revitalize regional economies, thus drawing attention to the use of timber in check dams. However, comparisons between timber and concrete check dams, in terms of their impact on the regional economy, have been overlooked in previous studies. Therefore, targeting Akita Prefecture in Japan, we evaluated quantitatively the respective regional economic impac

Abstract:
Identifying and extracting check dams is of great significance for soil and water conservation, agricultural management, and ecological assessment. In the Yellow River Basin, the check dam, as a system, generally comprises dam locations and dam-controlled areas. Previous research, however, has focused on dam-controlled areas and has not yet identified all elements of check dam systems. This paper presents a method for automatically identifying check dam systems from digital elevation model (DEM) and remote sensing images. We integrated deep learning and object-based image analysis (OBIA) metho

Abstract. Slot-check dam system is commonly used to control sediment transport associated with debris flows and mitigate debris flow hazards. This paper aims to estimate the performance of the slot-check dam system in the field and set up a verification to evaluate the efficiency of a slot-check dam system and each subsystem in debris flow sediment control. Field survey on a group of a series of slot-check dams at Shengou Basin in Yunnan, China reveals that the conserving sediment volume of each dam is related to its relative location in the group, gradually decreasing from upstream to downstr

Abstract:
Check dams play an irreplaceable role in soil and water conservation in the Chinese Loess Plateau region. However, there are few analyses on the connection between check dams and the downstream channel and the impact on structural connectivity and sediment interception efficiency. Based on a field survey, this study classified the connection mode between check dams and the downstream channel, and the actual control area percentage by discharge canal in dam land was used to quantitatively evaluate the degree of the structural connectivity of sediment between the check dam and the downstream cha

Abstract In the past decade, incidents of peatland fires have occurred in Malaysia, especially during the prolonged dry weather between February to May and July to October of each year. The canal blocking system or check dam is commonly used to control water tables in peatland. The objectives of this paper are to review the common check dam used for peat fire management. Next to propose a suitable check dam for peat fire management and to prepare a Sketchup model. The case study at Ayer Hitam Forest Reserve (AHFR) is located in the district of Muar, Johor State, with a total area of 3,797 ha.

Abstract:
Investment in the small-scale enhancement of groundwater recharge through check dams and other recharge structures in rural India is on the order of USD 1 billion/year. However, for any catchment, the optimal capacity of check dams is unknown, and the impacts on downstream flows are rarely determined. This paper describes a method that can be applied to plan recharge augmentation in catchments that have at least one monitored check dam. It was applied in the Dharta catchment of the Aravalli Hills in Udaipur district, Rajasthan, India, where four check dams in an ephemeral stream were monitored

Abstract:
As the primary ecological construction measure on the Loess Plateau, check dams play an essential role in developing agricultural production, improving people’s production and life, and replenishing groundwater. Soil water infiltration is the most important way to replenish groundwater in the dam land. In order to investigate the water infiltration process of check dams, an empirical model suitable for the simulation of the dam land infiltration process was selected. The soil water infiltration process of the check dam was studied by a field test and a model simulation. The results showed that

Abstract:
Check dams are among of the most widespread and effective engineering structures for conserving water and soil in the Loess Plateau since the 1950s, and have significantly modified the local hydrologic responses and landforms. A representative small catchment was chosen as an example to study the influences of check dams. A physics-based distributed model, the Integrated Hydrology Model (InHM), was employed to simulate the impacts of check dam systems considering four scenarios (pre-dam, single-dam, early dam-system, current dam-system). The results showed that check dams significantly alter t

Abstract:
The regional economic impacts of the construction of timber and concrete check dams in Akita prefecture, Japan, were compared. When functions are appropriately unified, a concrete check dam is cheaper to build than a timber one; the difference in construction costs can be used by the government to issue premium vouchers as a regional promotion measure. To evaluate the effect of this, we extended the latest input–output table for Akita Prefecture to include timber and concrete check dam construction sectors. Concrete check dam construction with premium-voucher issuance had a total effect of 46,
