In the paper "Assessment of the dynamic impact of debris flow on structure safety: A case study of check dam in Vietnam" the stability of a check dam located in Vietnam is re-evaluated in two regimes of the debris flow impact: (i) static impacts as conventional flood flow and (ii) dynamic impacts adopting Huebl’s approach. The results help to analyze shortcomings of the current design procedure applied for checking dams in particular and hydraulic structures in general.

Ebook "Functional and ecological xylem anatomy" will describe the xylem structure of different plant groups, and will put the findings in a physiological and ecological context. For instance, when differences in vessel diameter are featured, then there will be an explanation why this matters for water transport efficiency and safety from cavitation. The focus is on the hydraulic function of xylem, although mechanical support and storage will also be covered.

Ebook "Modelling water flow in unsaturated porous media: Accounting for nonlinear permeability and material heterogeneity" focuses on two issues related to mathematical and numerical modelling of flow in unsaturated porous media. In the first part numerical solution of the governing equations is discussed, with particular emphasis on the spatial discretization of highly nonlinear permeability coefficient. The second part deals with large scale flow in heterogeneous porous media of binary structure.

The scarcity of natural sand for construction in the current circumstance has made researchers and engineers search for another resource to replace it. This paper presents a study on the influence of crushed sand and natural sand on the properties of self-compacting concrete (SCC) implemented for the Dong Nan Ren irrigation project-Bac Lieu province.

In this paper, the Da Lat Nuclear Research Reactor (DNRR) core has been modeled by SCALE/TRITON code to generate two-group homogenized cross-sections for 3D kinetics calculations. In the calculation, plate-type model has been applied in selfshielding structure while the fuel assemblies have been grouped for the cross-section generation.

Hanoi city has abundant groundwater, supplemented by the surface water (mainly Red river) all year round, and the extensive shallow aquifers, which are easily exploited by large-diameter wells. There always exists some open hydrogeological windows in the Red river area with an open structure; therefore, the groundwater has a strained hydraulic relationship with the Red river water system Along the Red river from Ba Vi to the end of Phu Xuyen district, there are nine regions with three types and four sub-types of different hydrogeological structures.

In this research, the study of the final geometry in abrasive waterjet machining of a hybrid CFRTP/Steel structure. A new methodology for the evaluation of taper angle with high accuracy has been developed through image processing. In addition, the surface quality in terms of Ra and Rz has been assessed. A potential-type trend between taper and hydraulic pressure has been established for both materials.

In this paper, a control algorithm for controlling the position of the EHA is designed. In this controller structure, the system uncertainties are lumped into two unknown time-varying functions. The boundary of one of the unknown functions is not available. An approximate technique is used to express the unknown function as a finite combination of basis function.

Weirs are overflow structures used to measure flow or to control the water elevation. In sharp crested weirs sharp edge in the crest causes the water to spring clear of the crest and thus accurate measurements can be made and results beneficial to tail end farms in a field channel. Hence, sharp crested weirs are used for experimentation. The research project was envisaged with the following objectives to develop sharp crested rectangular weirs with 30°, 45° and 60° edge angles.

Seawalls have been erected to protect hundreds of towns and tourism areas stretching along the coast of Vietnam. During storm surges or high tides, wave overtopping and splash-up would often threaten the safety of infrastructures, traffic and residents on the narrow land behind. Therefore, this study investigates these wave-wall interactions via hydraulic small scale model tests at Thuyloi University. Remarkably, the structure models were shaped to have different seaward faces and bullnoses.
