Weirs, as overflow structures, are extensively used for the measurement of flow, its diversion and control in the open canals. Labyrinth weir due to more effective length than conventional weirs, allows passing more discharge in narrow canals. Determination the design criteria for the practical application of these weirs need more investigation. Weir angle and its position relative to the flow ...

Local scouring in the downstream of hydraulic structures is one of the important issues in river and hydraulic engineering, which involves a lot of costs every year, so the prediction of the rate of scour is important in hydraulic design. Side weirs are the most important of hydraulic structures that are used in passing flow. This study investigate the scouring due to falling jet from side weir...

In this study an extensive experimental research is carried out to develop a better understanding of the effects of Piano Key (PK) weir geometry on weir flow threshold submergence. Experiments were conducted in a 12 m long, 0.4 m wide and 0.7 m deep rectangular glass wall flume. The main objectives were to investigate the effect of the PK weir geometries including the weir length, weir height, ...

Crump interprets the stories, rather than simply recounting them. Her background as a research biologist, and her fi eld experience with native peoples, give her a broad perspective on the topic. She weaves a deft blend of summary and commentary, and often returns to emergent themes. Why do particular species appear in leading roles? Why do snakes and toads so often end up both as hero and vill...

TRIAL SUMMARY: GDP less toxic but equally effective relative to DHAP. Crump M, Kuruvilla J, Couban S, et al. Gemcitabine, dexamethasone, cisplatin (GDP) compared to dexamethasone, cytarabine, cisplatin (DHaP) chemotherapy prior to autologous stem cell transplantation for relapsed and refractory aggressive lymphomas: final results of the randomized Phase III NCIC CTG study Ly12. Presented at aSH...

Labyrinth weirs are utilized to transport a greater discharge during floods in contrast conventional due their increased weir crest length. Nevertheless, the geometric complexity of labyrinth weirs, determination accurate coefficients and accordingly, head-discharge ratings quite essential issues practical application. Hence, as first step present study proposes following eight standalone algor...
