Use Of Peak Discharges In Flood Frequency Analyses, Fati̇h Topaloğlu, Ali̇ Yücel, Kazim Tülücü, Mahmut Çeti̇n

Turkish Journal of Agriculture and Forestry

Hydrological data such as daily, monthly, and yearly peak discharge rates, ... etc., are being used in flood frequency analyses. Because the phenomena have inherent random character, the value to be observed in the future can only be determined by probabilistical and statistical laws. This kind of data should show independent, homogeneous and random behavior so that it can be used in the simulation and frequency analyses. In this study, initial stage studies needed to be done and some simple basic statistical analysis techniques have been examined so that observed discharge data in an example river basin could be used …

Examining Statistical Sufficiency Of Rainfall Intensities At Standard Times Of Adana, Ali̇ Yücel, Fati̇h Topaloğlu, Kazim Tülücü Jan 1999

Examining Statistical Sufficiency Of Rainfall Intensities At Standard Times Of Adana, Ali̇ Yücel, Fati̇h Topaloğlu, Kazim Tülücü

Turkish Journal of Agriculture and Forestry

Hydrological and meteorological events are effected from different factors. Their values in future can only be determined by probability and statistical laws because rainfall intensities at standard time occurring under different eftects are random character. However, these values not being random character can not be used in their present situation in system simulation, frequency analysis, watershed amelioration, drainage studies, urban settlement planning, etc. In this study, it is aimed to examine some statistical analysis techniques thought to be helpful in deciding sufficiency of rainfall intensities at standard times in studies in questions. Depending on this aim, 14 rainfall intensities at …

Turkish Journal of Agriculture and Forestry

In this study, some cytological characters of orchardgrass were examined naturally growing in Erzurum. Plants assessed for their chromosome number were tetraploid (2n=28). In metaphase I stage the most prevalent pairing was bivalents (avg. 8.37). This was followed by quadrivalent (avg. 2.81), univalent (avg. 0.04) and trivalent (avg. 0.015) pairings. All combinations of bivalents and quadrivalents were recorded. In most of anaphase l cells examined chromosomes distribution to poles were even (14: l4), however some cells had laggings and bridges. In addition, 95. 17% of observed tetrads had no micronucleus.

Studies On Effects Of Russian Knapweed (Acroptilon Repens (L.) Dc) And Butter Cup (Ranunculus Damascenus Boiss And Gaill), Causing Problem In Winter Wheat, On Yield And Determination Of Their Economical Thresholds In Van, İlhan Kaya, Işik Tepe

Turkish Journal of Agriculture and Forestry

In this study, effects of different densities of Russian knapweed (Acroptilon repens (L.) DC) and butter cup (Ranunculus damascenus Boiss and Gaill) on yield and yield components of winter wheat were researched in Van. It was determinated that, increasing densities of A. repens have decreased number of spike, grain, straw and total yield of wheat. But, increasing densities of R. damascenus have not been effective on yield and yield components because of being small constitution and having short growing period. Ten plants per m^2 of A. repens reduced grain and straw yields respectively 24.3 and 19%. These amounts are over …

Without herbivory control, natural seed sources, and seasonal flood events, recovery of the Pen branch delta in South Carolina to former conditions (prior to thermal discharge) may take many years. To assess the recovery process, seedlings of baldcypress (TuxoLtiurn distichum), water tupelo (Nyssa aquatica), swamp blackgum (Nyssa sylvatica var. biflora), and green ash (Fraxinuspennsylucmicn) were planted in four areas of the delta in 1994. One-half of the seedlings were protected using tree shelters 1.5 m tall. Heights of seedlings were taken after planting and at the end of each growing season from 1994 to 1998.

Aboveground Production And Nutrient Circulation Along A Flooding Gradient In A South Carolina Coastal Plain Forest, William Conner, Marianne K. Burke, B Graeme Lockaby Jan 1999

Aboveground Production And Nutrient Circulation Along A Flooding Gradient In A South Carolina Coastal Plain Forest, William Conner, Marianne K. Burke, B Graeme Lockaby

Publications

Relative to effects of flooding, little is known about the influence of hydrology-nutrient interactions on aboveground net primary production (NPP) in forested wetlands. The authors found that nutrient circulation and NPP were closely related along a complex physical, chemical, and hydrologic gradient in a bottomland hardwood forest with four distinct communities. Aboveground biomass, NPP, biomass partitioning to stem production, growth efficiency, and soil macronutrient availability were greatest in the flooded zone, possibly because of the stable hydrologic regime. In the wet transition zone, trees were least productive, nutrient use efficiency was highest, and N retranslocation from foliage before abscission was …

Turkish Journal of Agriculture and Forestry

In this study the effect of fosetyl-Al against citrus root not and gummosis caused by Phytophthora citrophthora was investigated. The results showed that fosetyl-Al protected citrus from the disease at least for one year. It was found that two fungicide applications sufficiently protected the trees against citrus gummosis. No significant differences were obtained were obtained at two fungiciede dosages, 160 g a.i./100L and 200 g a.i./100L, in all applications. When the pathogen was inoculated two weeks before fosetyl-Al, the infection area was diminished and with time had complete recovery with callus formation. Thus, fosetyl-Al was shown to have a curative …
