Abstract There is a need of upgrading the old building stock with respect to thermal insulation envelope and specifically façades. are several systems on market, some quite new innovative. To bring down cost many based prefabricated moisture tight insulated units. This means that in case there barrier interior side, two barriers surround wall structure. The leakage driving rain into structure t...

Splash erosion is recognized as the first stage in the process of erosion that results in bombardment of the soil's surface with rain drops. Two basic processes in soil erosion are the dispersion of soil particles by rain drops and the changes caused to the soil's structure, which are then moved by runoff. In this research, the effect of various rainfall intensity (60, 90 and 120 mm/hr) on the ...

This study evaluates rainfall estimates from the Next Generation Weather Radar (NEXRAD), operational rain gauges, Tropical Rainfall Measuring Mission (TRMM) Multisatellite Precipitation Analysis (TMPA), and Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks Cloud Classification System (PERSIANN-CCS) in the context as inputs to a calibrated, distributed hy...

Commonly, military training games and simulations depend on participants engaging in the immersive environment and then stopping to glean the meaning of their behaviors through (admittedly, increasingly sophisticated) After Action Reports. In order to derive the meaning of their experience, they must break cognitive engagement with their experience. This is, of course, sub-optimal. While it is ...

Sixty-four different logging scenarios for an initially undisturbed forest stand at Deramakot (Malaysia) were simulated with rain forest growth model FORMIND. The scenarios differ regarding the logging cycle, logging method, cutting limit and logging intensities. We characterise the impacts with four criteria describing the yield, canopy opening and changes in species composition. Multicriteria...

Quantitative use of C-band radar measurements of reflectivity ( ) and differential reflectivity ( dr) demands the use of accurate attenuation-correction procedures, especially in convective rain events. With the availability of differential phase measurements ( dp) with a dual-polarized radar, it is now possible to improve and stabilize attenuation-correction schemes over earlier schemes which ...

In this study, the effects of three land use categories on runoff quality was investigated using a rainfall simulator, in six sub-catchments in Kakasharaf watershed in Lorestan province. In total, 39 instances of artificial rain with a duration 30 min were created and the amount of phosphorus and potassium in the resulting runoff was measured on three land uses. The results showed that the aver...
