Realtime flood propagation on the downstream of Bili-Bili reservoir with hydraulic routing

چکیده
On January 2019, the biggest flood in last decade struck Gowa and Makassar. The claimed enormous number of victims caused severe damage to many buildings; this can be anticipated by Flood Routing. This study aims analyze hydrograph, propagation time, determine inundation model during downstream Bili-Bili reservoir. research was conducted through three phases: delineation watershed using ArcGis 10.6.1, hydraulic routing HEC-HMS 4.5, simulation HEC-RAS 5.0.7 integrated with RAS-MAPPER. results indicated that hydrographs occurring upstream 3,319.7 m3/s 2.961.4 m3/s, travel time flooding lasted for 1 hour 44 minutes, as well a realtime reservoir produced surface area 52.47 km2.

Reservoir Routing on Double-Peak Design Flood
This work investigates the routing effect provided by an artificial reservoir to a double-peak flood of a given return period. The present paper introduces a dimensionless form of the reservoir balance equation that describes the hydrologic-hydraulic processes that may occur and allows for the evaluation of the reservoir routing coefficient (RC). Exploiting this equation, an extensive sensitivi...
متن کاملBili Inhibits Wnt/β-Catenin Signaling by Regulating the Recruitment of Axin to LRP6
BACKGROUND Insights into how the Frizzled/LRP6 receptor complex receives, transduces and terminates Wnt signals will enhance our understanding of the control of the Wnt/ss-catenin pathway. METHODOLOGY/PRINCIPAL FINDINGS In pursuit of such insights, we performed a genome-wide RNAi screen in Drosophila cells expressing an activated form of LRP6 and a beta-catenin-responsive reporter. This scree...
متن کاملEffect of Hydraulic Fracture on the Fractured Reservoir Based on the Connection with Natural Fractures
Hydraulic fracturing in the fractured reservoirs plays a significant impact on the production rate. In this study, the hydrostatic condition is taken into account, the hydraulic fracturing operation was applied in every direction usinga written distinct element code. In each direction the hydraulic fracture is applied with different lengths and in each level the amount of production is predicte...
متن کاملReactions of Bili-Uele chimpanzees to humans in relation to their distance from roads and villages.
In order to assess the impact of human activities on chimpanzee behavior, we compared reactions to humans of Eastern chimpanzees (Pan troglodytes schweinfurthii) living in proximity to and at a distance from roads and settlements in the Bili-Uele landscape in Northern Democratic Republic of the Congo (DRC). We found that chimpanzees in the remote Gangu Forest were more likely to show curious or...
متن کاملPlace de la bili-IRM dans le diagnostic etiologique des icteres cholestatiques à Dakar
La Bili-IRM est une méthode diagnostique d’introduction relativement récente dans l’arsenal d’exploration de la pathologie bilio-pancréatique. Il s’agit d’une technique fiable reproductible et non invasive, permettant la visualisation directe des voies biliaires et pancréatiques. Le but de ce travail était d’étudier les aspects morphologiques des principales anomalies et d’évaluer la place de l...
