DearProfessorDenev:
AssociateProfessorI)r. Eng. Krasimir Velkov Petrov
It is a privilege and an honorto write in supportof Dr. Krasimir Petrovof the University of
Architecture"Civil EngineeringandGeodesyforpromotion to the rank of Professor.I write
partioularlyfrom the perspectiveof my internationalinvolvementwith Dr. Pefiov; other
colleagueswill be in a betterpositionto evaluatehis professionalcompeteircyand
productivity in Civil Engineering,which I am sureis unquestioned.
I haveknorrn Dr. Petrovsince 1995when I was a Fulbright Professorand interim vice-rector
at the AmericanUniversity in Bulgaria.We both attendedpublic hearingson the
controversial"Djerrran-Skakavitsa"projectheldin SaparevaBanya.I was impressedthenby
his scientific ability andpublic communications.
Subsequently,I was editor of a specialjoumal issueof Gea./ournal(Netherlands)on water
nssorrcesof Bulgaria.A submissionby Dr. Petrovwith his graduatestudentNicolas
Kathijoteson "Use ofNon-ConventionalWater for lrrigation During lhought in Bulgaria"
was very positively reviewedandincludedasa valuablepart of that specialiszuein 1996.
Basedon Dr. Petrov'sprofessionalability andexpertise,he was askedin 1998to be a
reviewerof a book proposalto Kluwer publicationson "Managementof ScarceWater:
Optimizationof irrigation Water in the JordanValley''submitted by RadwanA. Al-Weshah,
PhD. Dr. Petrovalso servedasa r€viewerof an manuscripton "WatetrResourceImpactsof
Climate Changein SoulhwesternBulgaria" fot Gealourrutl in 2001.
I penonally nominatedDr.Pefrovasa pte-publicationreviewerfor the boolq "3aqrutaeouemo
a Baneapun:ffiIreilewev aHatnoe
aa KrnawatmlruHu
rynileHu (Sofia: BulgarianAcademyof
SciencesPress,2m3). This book was subsequentlypublishedasDroaght in Bulgaria: A
Contemprary Analog of ClimateChangein Aldershot,uK in fte seriesAshgateStudiesin
EnvironmentalPolicy andhactice. Dr. Petrov'svaluablecommentson the Bulgarianbook
helpedto strengthenthe subsequant

In additionto theseimportantintemationalpublicationsupportactivities,Dr. Petrovwasthe

visit to UACEG, fh. Petrovcollaboratedwith him in offering a courseto UACEG students
on modelsof non-pointpollution in nral areas,aswell asa scientific seminaron the same
andpmfessors(all in 1999).
topic for Bulgarianresearchers
In additionto theseinternationalactivities,in 2007 I hadthe privilege of reviewingthe
doctoraldissertationoffh. Petnov'sstudentIrenaMadimirov4 an excellentapplicationof
geographicinformation systems(GIS) at a nationallevel in relationto nitogen grormdwater
pollution in Bulgaria.
Beyondtheseactivities,Dr. Petrov(andhis studentDn Vladimirova) gavelectureson water
andpollution issuesto visiting goups of Americanstudonts,including hostingthem to see
the GIS work at UACEG. Dr. Petnovalsohelpedto facilitate my participationandmy
colleaguesin conhibutingto the "'AnniversaryScientific Conferencg50 YearsFaculty of
Hydrotechnicsat UACEG."
This brief summaryof intonational andscholarlyactivitiesof fh. Petrovspeaksstronglyto
both his professionalabilities andhis role as a contibutorto, and cataly$ for, significant
internationalcollaborations.It doesnot surpriseme at all that colle4guesat UACEG have
supportedhis role as a Deanandlater asVice Rectorat UACEG.
Let me closeby briefly speakingof my own qualificationsto write. I servedasfaculty at the
PennsylvaniaStateUniversity from 1971,working on resouncemanagementandwater.I arn
an electedFellow of the AmericanAssociationforthe Advancementof Scienceaswell as
SigmaXi. I washeadof the Departrrentof Geographywhosegraduateprogramwas at that
time rankedfirst nationallyby the U.S. National Academyof Scieirces.I alsoservedasa
vice-provost headof a major climate changeresearchpnogrttm,and chair of the University
Faculty Sqrateat Pqrn State.I am authoror editor of ten books(six of which relateto
Bulgaria); authorof well over I l0 publications,chaptersandreviews;gave 135serninarsand
professionalpresentations:andwrote morc than 40 researchreports.I was directorof the first
Gl$-basedmodel in a researchproject in Bulgaria (on the StrumaBasin).
On the basisof my own perspectivesandthe work of Dr. Krasimir PetrovasI know if he is
well qualified for recognitionasProfessor.I commendhim to you for this promotionwithout
hesitation.
Sincerelyyours,
W
