EFFECTS OF INCREASED LAND USE CHANGES ON RUNOFF AND SEDIMENT YIELD IN THE UPP...IAEME Publication
River Nzoia originates from three water towers namely Nandi hills, Cherengany Hills and Mount Elgon. With increased anthropogenic activities in Nzoia river catchments, land cover has continuously been altered. This scenario has resulted into increased quantity of physical parameters in runoff among them, sediment load and turbidity, during rainy season. This study modelled effects of increased land use changes on runoff and sediment loads. Digital Elevation Model, spatial soil data, sediment loads and meteorological data for the year 2000 to 2012 were the main input into the Soil Water Assessment Tool (SWAT 2012) model for calibration and validation
Presentation powerpoint -Danube Delta .The greater part of the Danube Delta lies in Romania (Tulcea county), while its northern part, on the left bank of the Chilia arm, is situated in Ukraine (Odessa Oblast). The approximate surface area is 4,152 km², and of that, 3,446 km² are in Romania. With the lagoons of Razim-Sinoe (1,015 km² with 865 km² water surface), located south of the main delta, the total area of the Danube Delta reaches 5,165 km². The Razelm - Sinoe lagoon complex is geologically and ecologically related to the delta proper and their combined territory is part of the World Heritage Sites.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

short intervals
Hydropower versus Flood control in dam and basin management levels
3. The inundation in Shkoder
In early December heavy rainfall in the catchments of the Drini River
and Shkodra Lake led to flooding of an estimated 14,500 ha of farmland
and settled areas including the city of Shkodra, within Shkodra
Prefecture.
It has been reported that 4,600 houses have been directly affected by
the flooding, causing the evacuation of some 12,145 people. A further
14,646 livestock were also evacuated during the peak period of
flooding.
No deaths or casualties directly related to the flooding have been
reported

15. Drini & Buna River Basin
Buna 41 km long
Mean annual flow 680 m3/sek
From Shkodra lake 320 m3/sek
From Drin 360 m3/sek
Floods are natural phenomena in the
Drini/Buna basin
Excessive snow melt in the Drini River headwaters (which occurs in January-March months);
High rainfall in lower reach of Drini Basin causing to Drini River to have high flows; and/or
High rainfalls in Drini and over the Lake Shkodra Basin can cause combined flows of Drini and
Buna Rivers to have high flows which over top the Buna River Banks
16. Drini & Buna River Basin
• Drin is the biggest river in Albania with a total length of
about 450 km
• Drin 160 km
▫ White Drin 170km
▫ Black Drin 120 km
• Black Drin sources from Ohrid Lake which soruces from
Prespa Lake

If the water level at Koman Dam downstream of Fierze is more than 170 m
a.s.l. the water from Fierza dam can be discharged only by full operation of the
turbines, about 550 m3/sec
According to the discharge regulation for the three dams in Drin River, in
winter discharge tunnels should be opened at 290m a.s.l. at Fierza dam and
the water level must not be increased at 296 m a.s.l.
Because of possible landslides. Fierza dam has a 15 m freeboard to resist the
possible increase of the volume and height of wave to be created.

35. Flood Management
Buna River and Shkodra Lake are considered as
International waters. Nothing was done by the two
countries, for the last 20 years, to increase the
management of this vital water sources
Since the January 2010 flood, Albanian and Montenegro
Governments have intensified their collaboration in
finding solutions in benefit of both countries and the
population affected
The two countries are seeing the possibility of
deepening the Buna River bed and cleaning the sea
outfall
36. Flood Management
There was no advertising from measures on
White Drin or Black Drin outside of Albanians
border on increase on rainfall, following in few
days an increase of flow.
There was no advertising from Spile HPP on
discharging schedules (to my knowledge)
Problem to be solved on preparing an integrated
management system on the hole Drin system
37. Flood Management
Prespa Lake
Ohrid Lake
Black Drin

BASIN MANAGEMENT BETWEEN GREECE, FYROM,
KOSOVA AND ALBANIA MUST BE PUT IN PLACE
38. Flood Management
Construction of Ashta HPP, downstream of
Vau I Dejes is very different from Bushati
study with a dam and a small reservoir
Nothing can be done at this stage
39. Flood Management
Construction of Skavica HPP, up stream of
Fierza with a big reservoir would not only
increase by about 30% the production of
Drin cascade (within Albanian border) but
will also do perennial regulation of Drin
flow
This is one of the priorities of Albanian
Government in the field of Safety and Power
Production
40. Flood Management
Albania Power Corporation (KESH) was
producing at the maximum possible during
the flood, but the system couldn’t supported
all the energy produced by KESH
Problem solved during this year a new
interconnection line with Montenegro
integrates better Albania with Regional
Network.
41. Flood Management
Buna River has 31 km of dikes which didn’t
performed according to their purpose.
Albanian Government has invested just during
2011, about 10 million USD on dikes and drainage
system rehabilitation/improvement
(reference from Ministry of Agriculture officials)
Albanian Government in collaboration with World
Bank is in process of a study to analyze the
hydraulic characteristic of Shkodra Valley to
determine the best long term solution on floods
